239e253057 Make ad directory name tunable, adapt to kleinanzeigen.de site changes
Add template for ad name, adapt kleinanzeigen.de changes
2024-01-12 14:56:08 +01:00
cdf58efd45 fixed changes on kleinanzeigen.de:
- Meta did not contain condition and category together anymore, they
removed  the category. Therefore fetching (that is, validation)
failed.
- Now we extract the condition and category directly.
- On top, category now includes the whole category tree.
- unit tests had to be tweaked for this measure.

To install after building either copy the binary or execute `sudo make install`.
### Using the docker image
A pre-built docker image is available, which you can use to test the
app without installing it. You need `docker-compose`. Copy the file
`docker-compose.yaml` to somewhere, cd to that directory and execute:
```shell
mkdir kleinanzeigen-backup
USER_ID=$(id -u) GROUP_ID=$(id -g) OUTDIR=./kleinanzeigen-backup docker-compose run kleingebaeck -u XXX -v
```
`USER_ID` and `GROUP_ID` needs to be specified so that you are the
owner of the created backups. The backup directory `OUTDIR` must exist
prior to the execution, otherwise docker will create it as root, then
kleingebaeck will fail. You may also use a `.env` file in the same
directory containing the variables, such as:
```
USER_ID=1000
GROUP_ID=1000
OUTDIR=./kleinanzeigen-backup
```
You may of course also modify the `docker-compose.yaml` to suit your needs.
If you want to build the image yourself, use the supplied Dockerfile.
## Commandline options:
